A scientist whose observations of drowned polar bears raised alarms about climate change has received $100,000 to settle a whistle-blower complaint against an agency of the Department of the Interior.

Under the settlement, wildlife researcher Charles Monnett retired from his job at the federal Bureau of Ocean Energy Management ...

Evolution is relentless process that seems to keep going and going, even when creatures live in a stable, unchanging world.

That's the latest surprise from a unique experiment that's been underway for more than a quarter-century.

Evolution is so important for biology, medicine and a general understanding of our world ...

A team of planet hunters estimates that about 22 percent of the sun-like stars in our galaxy may have planets about the size of Earth that are bathed in similar amounts of sunlight — and potentially habitable.

That's the conclusion of a new analysis of observations taken by NASA's Kepler ...

Dogs can pick up emotional cues from another dog by watching the direction of its wagging tail, a new study suggests.

In a series of lab experiments, dogs got anxious when they saw an image of a dog wagging its tail to its left side. But when they saw a ...

Charles Monnett's 2006 report on drowning polar bears became a rallying cry for environmentalists. Then he was accused of scientific misconduct. On Friday, he learned he had been cleared.

NASA's newest Mars rover snapped photos of rocky outcroppings that jut out from the alien soil. Scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.

One of the twin space probes launched 35 years ago has traveled more than 11 billion miles from Earth. The Voyager probes were originally slated just to examine Jupiter and Saturn during a five-year trip.

So far everything looks good for a possible docking with the station on Friday by the company's Dragon capsule.

The first of NASA's retired space shuttles will make its way to its new retirement home on April 17. The well-traveled orbiter will be flown low over the nation's capital before being...

Last month, scientists around the world agreed to temporarily halt certain genetic experiments with bird flu viruses. More than three weeks of that 60-day moratorium have already passed. And the scientific community is in the midst of a fierce debate about what needs to happen next.

The suspension of the ...

In a landmark decision, an expert panel that advises the government on research security says key details of work on the contagiousness of flu viruses should not be published openly. I

The planet, dubbed Kepler-22b, isn't much larger than Earth and is orbiting a star in a region that's not too hot and not too cold — just the kind of place that could be home to liqui...
